Which firmware can be used

kdFi:
The hardware of the kdFi is compatible with every version of the MS2extra firmware.
However, only for Megasquirt, do not download Microsquirt or any other version.

UAB:
The UAB hardware only works with the standard MS3 firmware; do not load Pro, Ultra or any other version.

The appropriate MSQ file can be downloaded under Download.

We recommend leaving the factory loaded firmware as long as you do not miss a special function that is included in a newer firmware.

Settings error or misfiring can NOT be solved by a firmware update.
